Phantasmagoric Ignited Foxy or just in short Ignited Foxy is a supernatural hallucination seen in the Extras Menu. He is an alternation of Ignited Foxy. Not much is known about him other than that he is a hallucination.

Behaviour

There are actually multiple Phantasmagoric Ignited Foxy's in the last
stage of the Extras challenge. All of them are completely static in a fully black room with no light source except the light from the ditto's.

If you turn around to exit when you enter the mysterious room, you will be greeted by Phantasmagoric Ignited Foxy's jumpscare, ending the Extras challenge, and crashing the game. For a flash second after his jumpscare, one would spot three words 'Come Back Later'.

Trivia

It is unknown what the words "Come Back Later" mean. However, it is possible the words mean to come back when story mode is made, In Story mode, whenever you die, it will say come back later, so that might be a reference

Many fans suggested theories.

8Bit-Ryan, a YouTube Let's player, thought that it meant to reload the game. It didn't work.
